They define and discuss validity and reliability; proceed to a discussion of three basic types of validity, including criterion, content, and construct validity; present an introductory discussion of classical test theory, with an emphasis on parallel measures; and present a clear discussion of four methods of reliability estimation, including the test-retest, alternative form, split-half, and internal consistency methods of reliability assessment.
